In short, this mod is a difficulty booster, and implements most of the 'features' from Shadow of Chernobyl as a way of adding variety to the game, without adding weapons or armors that don't canonically fit. Most that aren't quest rewards are carried by specific stalkers whom you must kill, or are used by the appropriate faction's experts to give them a definitive 'punch' that CoP's characters and experts lack compared to previous games. There are no new caches or random lockboxes hidden in plain sight for the player to find - most of the new content is unlocked as quest rewards, or from Owl and Hawaiian's expanded inventory (which also gives a little bit more incentive to pick a side and stick with it in the faction war). The point of this modification is to add to the game, in more subtle ways then most other mods have done. I'd like to get some feedback on the ideas being implemented, so I can snip bits that would detract from the game.
Now, thanks to a week off from school, I've brought the quality up to a level that the mod is nearly release-ready. I've been working bit by bit on a modification since I got my hands on the Russian version of Call of Pripyat.
